I think that's a pretty patronising take on Poch.
He was a worthy applicant for the job. His stock has skyrocketed because of himself. His backroom team, his methods, his philosophy, the culture he creates, and his tactics and training. Many hours of study, research, dedication and plain hard work got him (and us) to the heights we did. I fail to see any 'luck' in that.
And I'd hazard a guess that if you said it to the man's face, he'd give you a slap
We will see, no doubt Poch gave it his all, but sometimes people are just the right fit at the right time in the right place. See Harry as another example, how many decades of management yet his stint here was way above anything else he ever did.
It will be very interesting to see how much he "overachieves" in his next role.
People love the narrative of Levy holding back his managers yet Jol, Harry, AVB, Poch (so far admittedly) have all performed above their career average here ..
